Agent Memory MCP has well-structured tool definitions with consistent naming (verb_noun pattern: memory_store, memory_search, etc.) and reasonable descriptions (avg ~150 chars). All 8 tools have input schemas with typed parameters and descriptions. However, output schemas are not documented, LLMs cannot predict what fields to expect from responses. Parameter descriptions lack constraint details (e.g., 'max 50,000 chars' for content is stated but format/range specs are sparse). Error handling is minimal, no recovery guidance or actionable error messages visible. The memory_delete tool (destructive) lacks confirmation/dry-run pattern. Tool composition is sound (single responsibility), but missing pagination guidance for list/search despite FTS5 support.

• Document output schemas for all tools. E.g., memory_search should specify: returns array of {id: int, content: string, type: string, tags: string, importance: int, created_at: ISO8601, accessed_count: int}. memory_list and memory_stats similarly.
• Add confirmation/dry-run pattern to memory_delete. Offer a 'dry_run' boolean param or require explicit 'confirm_delete: true' to prevent accidental destruction.
• Enhance pagination: add 'offset' param to memory_list, document 'total_count' in response, and add 'next_cursor' guidance for memory_search to support large result sets.
• Clarify parameter constraints in descriptions. E.g., 'importance: Rating 1-5 where 1=low priority, 5=critical. Default 3 (normal).' For tags: 'Comma-separated, max 10 tags, each 1-50 chars.'
• Add error handling guidance. Document common failures (DB locked, invalid query syntax, memory not found) and recovery steps. E.g., 'If memory_search returns no results, try broader terms or call memory_list to discover available memories.'
